Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal communication processing that is carried out with a DTE control part and a DCE control part kept in the reverse connection states by deciding the reverse connection when no signal cannot be detected and performing the control to reset a voice mode. SOLUTION: When an control signal of an OK or NO CARRIER signal is received in a response reception mode, a TDM(time division multiplex) communication system device 4a starts a flag 3-byte detecting operation and checks whether a flag 3-byte of 300bps is detected again. If the flag 3-byte is detected, the reverse connection is decided and a control signal (ATHO) is sent to a TDM device 4b. Thus, a communication operation itself is not finished and a timer 6 is set at 600ms. When the timer 6 has a time-out, a request signal RQ2 is sent to the device 4b from the device 4a. Then the device 4a itself is switched to a FAX reception mode from a FAX transmission mode.
